[0032] (2) The continuous stamping molding mechanism of the high-sealing pesticide bottle cap receives power from the linkage assembly through the first bevel gear at one end of the reciprocating screw, and then the reciprocating screw rotates. Due to the action of the thread, the reciprocating translation frame will move back and forth laterally along the axial direction of the screw, thereby causing the stamping assembly, the pushing assembly and the lower die assembly to reciprocate synchronously, so that the stamping rhythm can be synchronized with the winding speed of the aluminum sheet, so that the stamping head and the aluminum sheet are in a relatively static state when they are in brief contact, avoiding the aluminum sheet from being squeezed and interfered with the stamping head during the winding process, thereby ensuring the accuracy and quality of the bottle cap molding.

[0033] (3) The continuous stamping die-forming mechanism of the high-sealing pesticide bottle cap has the following advantages: when the stamping is completed, the stamping head is lifted upward, and the mold core pushes out the molded bottle cap under the upward thrust of the spring, so that the bottle cap is separated from the mold core surface and stays on the top surface of the lower mold base, so that the pusher assembly can push it out later. The function of the limit column is to limit the displacement range of the mold core, ensure its stability and accuracy during the up and down movement, prevent the mold core from shifting or falling off the lower mold base, thereby ensuring the smooth progress of the stamping and demolding process.

[0043] See also Figure 1-7 The present invention provides a technical solution: a continuous stamping molding mechanism for a high-sealing pesticide bottle cap, comprising a base 1, on which a stamping mechanism is provided, the stamping mechanism comprising:

[0044] The winding assembly 2 includes a U-shaped frame 21. The number of the U-shaped frames 21 is set to two, and the U-shaped frames 21 are symmetrically installed at the edges of the top surface of the base 1 near the left and right sides. One of the U-shaped frames 21 is provided with a reel 23 for storing aluminum sheet blanks, and the other U-shaped frame 21 is provided with a reel 22 for receiving aluminum sheet waste.

[0045] A driving assembly 3 is arranged on one of the U-shaped frames 21, and the driving assembly 3 can drive the winding roller 22 to rotate to wind the aluminum sheet waste;

[0046] The reciprocating translation assembly 4 is arranged at a position near the middle of the top of the base 1. The reciprocating translation assembly 4 includes a reciprocating translation frame 41, and the reciprocating translation frame 41 can perform transverse reciprocating motion between the winding roller 22 and the unwinding roller 23;

[0047] The linkage assembly 5 is arranged between the base 1 and the reciprocating translation frame 41, and is connected to the driving assembly 3 and the reciprocating translation assembly 4. The driving assembly 3 can drive the linkage assembly 5 to operate. When the linkage assembly 5 operates, the reciprocating translation assembly 4 can operate, thereby realizing the reciprocating motion of the reciprocating translation frame 41.

[0048] The stamping assembly 6 is arranged on the reciprocating translation frame 41 and is connected to the linkage assembly 5. When the linkage assembly 5 is in operation, the stamping assembly 6 can be operated to achieve continuous stamping operation.

[0049] In this embodiment, the driving assembly 3 includes a motor 31 installed on the outer wall of the U-shaped frame 21, and a main shaft 32 is installed on the output shaft end of the motor 31. The main shaft 32 passes through the outer wall of the U-shaped frame 21 and extends to the other side, and the main shaft 32 is fixedly connected to the winding roller 22.

[0050] Specifically, the drive assembly 3 provides a power source for the entire stamping molding mechanism. The output shaft of the core component motor 31 drives the main shaft 32 to rotate. The main shaft 32 is fixedly connected to the winding roller 22, thereby transmitting the rotational power of the motor to the winding roller 22. Under the continuous drive of the motor 31, the winding roller 22 rotates at a constant speed to wind and collect the aluminum sheet waste after passing through the stamping area.

[0051] In this embodiment, the reciprocating translation frame 41 is set on the base 1 through sliding rails and sliders, and can slide laterally. Two groups of guide rollers 42 are symmetrically arranged on the reciprocating translation frame 41, and are installed on the inner bottom surface of the reciprocating translation frame 41 through brackets. There are two guide rollers in each group, and a channel for guiding the aluminum sheet is formed between every two guide rollers 42. A reciprocating screw rod 43 is threadedly connected to the bottom of the reciprocating translation frame 41, and the reciprocating screw rod 43 is installed on the top of the base 1 through two bearing seats, and a first bevel gear 431 is installed at the end of the reciprocating screw rod 43.

[0052] Specifically, after the first bevel gear 431 at one end of the reciprocating screw 43 receives power from the linkage assembly 5, the reciprocating screw 43 rotates. Due to the action of the thread, the reciprocating translation frame 41 will move back and forth laterally along the axial direction of the screw, thereby causing the stamping assembly 6, the pushing assembly 7 and the lower die assembly 8 to reciprocate synchronously, so that the stamping rhythm can be synchronized with the winding speed of the aluminum sheet, so that the stamping head 65 is in a relatively static state when it briefly contacts the aluminum sheet, thereby avoiding squeezing interference between the aluminum sheet and the stamping head 65 during the winding process.

[0053] In this embodiment, the linkage assembly 5 includes a first rotating shaft 51, a fixing frame 52, a shaft tube 53, a second rotating shaft 54 ​​and a third rotating shaft 55;

[0054] The first rotating shaft 51 is installed on the top surface of the base 1 through two bearing seats, and second bevel gears 511 are installed at both ends, one of the second bevel gears 511 is meshed with the first bevel gear 431, and a synchronous pulley set 56 is provided between the outer wall of the first rotating shaft 51 and the end of the main shaft 32;

[0055] The fixed frame 52 is installed on the rear surface of the reciprocating translation frame 41 near the bottom, and a third bevel gear 521 is rotatably provided on the fixed frame 52, and a flower shaft rod 522 is installed at the end of the third bevel gear 521;

[0056] The shaft tube 53 is movably sleeved on the surface of the flower shaft 522. The shaft tube 53 is installed on the top surface of the base 1 through a bearing seat. A fourth bevel gear 531 meshing with another second bevel gear 511 is installed at the end of the shaft tube 53.

[0057] The second rotating shaft 54 ​​is installed on the rear surface of the reciprocating translation frame 41 through two bearing seats, and fifth bevel gears 541 are installed at both ends of the second rotating shaft 54, and one of the fifth bevel gears 541 is meshed and connected with the third bevel gear 521;

[0058] The third rotating shaft 55 movably passes through the outer surface of the reciprocating translation frame 41 and is higher than the second rotating shaft 54 ​​. Sixth bevel gears 551 are installed at both ends of the third rotating shaft 55 , and one of the sixth bevel gears 551 is meshedly connected with the other fifth bevel gear 541 .

[0059] Specifically, the linkage assembly 5 serves as the transmission hub of the entire mechanism, and can distribute and transmit the power of the drive assembly 3 to the winding assembly 2, the reciprocating translation assembly 4, the stamping assembly 6 and the pushing assembly 7, thereby realizing the coordinated work of multiple components. When the motor 31 of the drive assembly 3 drives the main shaft 32 to rotate, on the one hand, the main shaft 32 directly drives the winding roller 22 to wind up the waste material, and on the other hand, it drives the first rotating shaft 51 to rotate through the synchronous pulley group 56. The second bevel gears 511 at both ends of the first rotating shaft 51 are respectively meshed with the first bevel gear 431 at the end of the reciprocating screw 43 and the fourth bevel gear 531 at the end of the shaft tube 53, thereby transmitting power to the reciprocating screw 43 of the reciprocating translation assembly 4, so that the reciprocating translation frame 41 can realize lateral reciprocating motion; at the same time, the power is also transmitted to the shaft tube 53, and then the third bevel gear 521 on the flower shaft rod 522 cooperates with the fifth bevel gear 541 at the bottom end of the second rotating shaft 54, so that the second rotating shaft 54 ​​rotates. When the second rotating shaft 54 ​​rotates, it can provide a power basis for the operation of the pushing assembly 7. At the same time, with the fifth bevel gear 541 at the top of the second rotating shaft 54 ​​and the sixth bevel gear 551 on the third rotating shaft 55, the third rotating shaft 55 and the sixth bevel gear 551 rotate, which can provide a power basis for the operation of the stamping assembly 6. This linkage mode makes the movements between the various components closely coordinated, realizing a continuous automated production process from aluminum sheet transportation, stamping to pushing, greatly improving production efficiency and reducing errors that may be caused by manual intervention.

[0060] In this embodiment, the stamping assembly 6 includes a fourth rotating shaft 61, which is installed on the inner wall of the reciprocating translation frame 41 through a bearing seat, a seventh bevel gear 611 meshing with another sixth bevel gear 551 is installed at one end of the fourth rotating shaft 61, and a rocker 612 is installed at the other end of the fourth rotating shaft 61, a first connecting rod 62 is rotatably provided on the rocker 612, and a lifting shaft 63 is rotatably provided on the first connecting rod 62, a shaft seat 64 is slidably provided on the outer wall of the lifting shaft 63, and the shaft seat 64 is installed on the inner wall of the reciprocating translation frame 41, and a punch head 65 is installed at the bottom end of the lifting shaft 63.

[0061] Specifically, after the seventh bevel gear 611 at one end of the fourth rotating shaft 61 receives the power from the linkage assembly 5, it drives the fourth rotating shaft 61 to rotate, and the rocker 612 at the other end of the fourth rotating shaft 61 rotates accordingly, and the rotational motion is converted into the up and down reciprocating linear motion of the lifting shaft 63 through the first connecting rod 62 and the lifting shaft 63, thereby driving the punch head 65 to perform a punching operation on the aluminum sheet located on the lower mold assembly 8.

[0062] In this embodiment, the stamping mechanism also includes a pushing assembly 7, which is arranged on the reciprocating translation assembly 4, and the pushing assembly 7 is connected to the linkage assembly 5. When the linkage assembly 5 is in operation, the pushing assembly 7 can be operated to automatically push out the stamped bottle cap. The pushing assembly 7 includes a support seat 71 and a synchronous wheel 72. The support seat 71 is installed on the rear surface of the reciprocating translation frame 41. The number of synchronous wheels 72 is set to two, one of which is fixedly sleeved on the outer wall of the second rotating shaft 54, and the other is rotatably arranged on the top of the support seat 71. A synchronous belt 73 is provided between the two synchronous wheels 72. The end of the synchronous wheel 72 away from the second rotating shaft 54 ​​is provided with a second connecting rod 74 near the edge through a shaft rotation. A telescopic rod 75 is rotatably provided on the second connecting rod 74, and the telescopic rod 75 slides through the rear surface of the reciprocating translation frame 41 and extends to the other side. A push plate 76 is installed at the end of the telescopic rod 75.

[0063] Specifically, when the second rotating shaft 54 ​​in the linkage assembly 5 rotates, the synchronous wheel 72 fixedly sleeved on its outer wall rotates accordingly, and drives another synchronous wheel 72 rotatably arranged on the top of the support seat 71 to rotate synchronously through the synchronous belt 73. The shaft rod at the end of the synchronous wheel 72 drives the second connecting rod 74 to make a circular motion. Since the second connecting rod 74 is rotatably connected with the telescopic rod 75, and the telescopic rod 75 slides through the reciprocating translation frame 41, under the movement of the second connecting rod 74, the telescopic rod 75 will make a reciprocating telescopic motion in the forward and backward directions. After the punch head 65 moves upward to complete the punching and demolding, the telescopic rod 75 extends out, and the push plate 76 moves forward accordingly, pushing out the bottle cap resting on the top surface of the lower mold seat 81, so that the bottle cap is separated from the mold area for collection, and when the punch head 65 moves downward for punching, the telescopic rod 75 retracts and the push plate 76 retreats to prevent the push plate 76 from interfering with the punch head 65 during the punching process.

[0064] In this embodiment, the stamping mechanism also includes a lower die assembly 8, which is arranged on the reciprocating translation assembly 4, and a channel for the aluminum sheet to pass through is formed between the lower die assembly 8 and the stamping assembly 6, and the lower die assembly 8 includes a lower die base 81, which is arranged between two groups of guide rollers 42, and the lower die base 81 is fixed to the inner bottom surface of the reciprocating translation frame 41 through a plurality of columns, a mold core 82 is provided in the inner cavity of the lower die base 81, a limiting column 821 is installed at the bottom end of the mold core 82, and the limiting column 821 slides through the inner bottom surface of the lower die base 81 and extends downward, a spring 83 is provided between the inner bottom surface of the lower die base 81 and the bottom surface of the mold core 82, and the spring 83 can generate an upward thrust on the mold core 82.

[0065] Specifically, during the stamping process, the punch head 65 moves downward to apply pressure to the aluminum sheet on the lower die base 81, so that the aluminum sheet is formed into a bottle cap under the shape of the mold core 82. When the stamping is completed, the punch head 65 is lifted upward. At this time, the mold core 82 pushes out the formed bottle cap under the upward thrust of the spring 83, so that the bottle cap is separated from the surface of the mold core 82 and stays on the top surface of the lower die base 81 so that the pushing assembly 7 can push it out later. The function of the limit column 821 is to limit the displacement range of the mold core 82, ensure its stability and accuracy during the up and down movement, and prevent the mold core 82 from deviating or falling off the lower die base 81, thereby ensuring the smooth progress of the stamping and demolding process.

[0066] See also Figure 1-7 The present invention also discloses a stamping film forming method of a continuous stamping die forming mechanism for a high-sealing pesticide bottle cap, which specifically comprises the following steps:

[0067] S1, raw material preparation, the aluminum sheet for making the pesticide bottle cap is wound on the unwinding roller 23 in the winding assembly 2, and the sheet is pulled to pass through the guide roller 42 on the left, the channel formed between the lower die assembly 8 and the stamping assembly 6, the guide roller 42 on the right, and finally wound on the winding roller 22;

[0068] S2, synchronous linkage, control the operation of the driving component 3, during the operation of the driving component 3, drive the winding roller 22 to rotate at a constant speed to pull the aluminum sheet, and at the same time, the driving component 3 also drives the linkage component 5 to operate, and through the operation of the linkage component 5, the reciprocating translation component 4, the stamping component 6 and the pushing component 7 are driven to operate synchronously;

[0069] S3, stamping and forming, during the operation of the stamping assembly 6, the stamping head 65 reciprocates up and down, so that the aluminum sheet between the lower die assembly 8 and the stamping assembly 6 is stamped and formed into a bottle cap;

[0070] S4, demoulding and discharging. After the stamping is completed, the punch head 65 moves upward, and the mold core 82 pushes the bottle cap out under the action of the spring 83, so that the bottle cap stays on the top surface of the lower die seat 81. When the punch assembly 6 is in operation, since the push assembly 7 is also running synchronously, when the push assembly 7 is running, the telescopic rod 75 will do a reciprocating telescopic movement in the front and back directions. When the punch head 65 moves upward, the telescopic rod 75 extends out, and cooperates with the push plate 76 to push out the bottle cap staying on the top surface of the lower die seat 81.
